A solenoid may refer to
  • Solenoidal vector field in mathematics, a vector field
    Vector field
    In vector calculus, a vector field is an assignmentof a vector to each point in a subset of Euclidean space. A vector field in the plane for instance can be visualized as an arrow, with a given magnitude and direction, attached to each point in the plane...

     characterized as having zero divergence
    Divergence
    In vector calculus, divergence is a vector operator that measures the magnitude of a vector field's source or sink at a given point, in terms of a signed scalar. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around...

  • Solenoid
    Solenoid
    A solenoid is a coil wound into a tightly packed helix. In physics, the term solenoid refers to a long, thin loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create...

    • a starter solenoid
      Starter solenoid
      A starter solenoid is the part of an automobile which relays a large electric current to the starter motor, which in turn sets the engine in motion...

      , part of an automobile ignition system; also called a starter relay
    • automotive transmission solenoid
      Transmission solenoid
      A transmission solenoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied via the transmission computer or controller...

    Solenoid (mathematics)
    In mathematics, a solenoid is a compact connected topological space that may be obtained as the inverse limit of an inverse system of topological groups and continuous homomorphisms...

  • Solenoid valve
    Solenoid valve
    A solenoid valve is an electromechanical valve for use with liquid or gas. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports...
